The Guardian wireless modem provides a high-speed data link suitable for a
wide variety of applications requiring system security and diagnostic reporting.
Designed for speed and efficiency, Guardian provides over-the-air data rates up
to 19.2 kbps in a 25 kHz channel.
Selectable operating modes provide flexibility: RS-232, RS-422, and RS-485
compatible; simplex, half-duplex or full-duplex operation; RTS-CTS handshaking
protocol or data activated transmission (DOX) mode.
Transparent, asynchronous
serial formats are supported, such as Modbus™, Modbus-RTU™, AB DF1™, and
various other protocol formats.
Guardian is also selectable for analog operation: paging, phone line substitution,
slow speed data applications, 600 ohm or high impedance audio input/output
selection.
Real-time, non-intrusive online diagnostics report received signal strength (RSSI),
RF power output, supply voltage, and other radio performance statistics.
